From libc_r:

int
_pthread_mutex_trylock(pthread_mutex_t * mutex)
{
	struct pthread	*curthread = _get_curthread();
	int	ret = 0;

	if (mutex == NULL)
		ret = EINVAL;

	/*
	 * If the mutex is statically initialized, perform the dynamic
	 * initialization:
	 */
	else if (*mutex != NULL || (ret = init_static(mutex)) == 0) {
		/*


from libthread_xu:

int
__pthread_mutex_trylock(pthread_mutex_t *m)
{
	struct pthread *curthread = tls_get_curthread();
	int ret;

	/*
	 * If the mutex is statically initialized, perform the dynamic
	 * initialization:
	 */
	if (__predict_false(*m == NULL)) {


Not sure if we are required to catch NULL pointers?  They shouldn't pass 
them in the first place...
